Is there a Sam wiki?
There is a knowledge base on the Ticket System website for contacting Spacial Support, but that doesn't explain any of the rotation types or selection methods.https://spacialaudio.zendesk.com/catego ... roadcaster
There is a Wiki, that is no longer maintained and has received it's last updates in the early days of SAM 4. This Wiki does not contain any explanation on the rotation types either.http://support.spacialaudio.com/wiki/Main_Page
The SAM manual is outdated as well and was last updated in 2006. However it is still the most valuable resource for learning the basics of SAM.
If you open the chapter "Reference Guides" and look at the section "Selection Method Logic" that explains the difference between the available selection methods.
The rotation types (Category/Weighted/Web scripting) are explained in the chapter "SAM Configuration" inside section "Playlist Rotation Rules".
The manual can not be opened from the SAM Help menu ever since Spacial redesigned their website, but the manual is still shipping with SAM as a file.
You can find the file in SAM's Program Files folder in the help subdirectory. It goes by the name SAM-BC.chm
